MACHINE FOR MAKING LOO'FED WIRE.

SPECIFICATION forming part of Letters Patent No. 300,550. dated June 17, 188%.

Application filed February 8, 188-1.

1'0 0955 10. 1.0712 it may concern:

Be it known that I, XV LLLiir WiLsoN, J12, of Grecnville, in the county of. New Castle and State of Delaware, have invented certain Iniproven'ients in Machines for Making Looped \V ire, of which the following is a spcciiication.

My invention relates to a class of machines which are used to twist a loop upon wire, and to out the looped wire to a given length, and which have for their object the rapid manufacture of looped sections of wire.

My invention is an improvement upon a machine for looping and cutting wire invented by me, and patented to me in and by Reissued Letters Patent No. 9,.LO L, dated October 12, 1880, the original of which Ileissued Letters Patent were issued on the 29th day of April, 1879, No. 214,977.

Reference is to be made to my ZIhOVBHZLlllGd Letters Patent for'a more clear understanding of my present invention, which relates more particularly to the devices for feeding the wire and to the devices for looping and cutting it. The improvements forming the suhjectanatter of this application are shownin the accompanying drawings as applied to my patented machine for looping and cutting wire, represented as constructed with its circular table or head which carries the twisting-hooks, and which operates in a vertical and not in a horizontal plane. Looped wire is used for various purposes in the arts-for instance, as an opening device formetallic cans, as a. means for securing tags, and for the baling of cotton, grain, and kindred substances.

My former patented invention consists, essen tially, ofaframe, (in the particular organization of that machine represented by the standard A,) which supports for revolution a circular table or head,whi ch carries a series oftwistinghooks operated by pinions secured thereto, which, at statcdintcrvals, engage with racks supported. from the frame, so as to revolve said hooks and twist the wire fed to them, and which also carries a corresponding series of cutting devices employed to cut the looped wire to given lengths. In that improved form of my patented apparatus which is represented in the drawings, the frame-work is, as stated, constituted by the standard A, while (X model.)

the table (or head, as it is more properly termed) B is set for revolution in a vertical plane. The wire feeding and twisting devices which constitute the particular points of invention in this application are hereinafter described and claimed.

In the accompanying drawings, which, as stated, represent my improvements applied to a wire looping and cutting machine, embodying in its arrangement a vertically-disposed revolving head, Figure l a front elevation of the entire apparatus. Fig. 2 is a rear elevation of the same. Fig. 8 is a sectional view of the wire twisting, cutting. and loop-discharging devices, the section being taken in a plane at right angles to the face of the head. Fig. t is an enlarged face view of the looping, cutting, and discharging devices. Fig. 5 is a perspective detail of the loop-discharging arm; and Fig. 6 a side elevation of the top of the standard, showing the bracket which supports the feed-arm. v

Similar letters of reference indicate corresponding parts.

In the drawings, A, as stated, represents the standard or supporting frame-work, and B the revolving head, which carries the wire looping, cutting, and discharging devices.

0 is the reel, upon which the wire to be looped is coiled, which is conveniently connected with the upper crtreniityot' the standard, and is controlled by a friction-brake device, W.

D is the feedarnnwhich is connected by the pivot d to a bracket, d, or kindred supporting device, sprung from the standard or other fixed point olsupport. The i'eed-armis adapted to be so inclined and adjusted that one of its extremities overhangs the face of the revolving head, while its other eXt-rcmityprthat whichis above its pivot, faces the periphery of the reel. Atits forward extremity the feed arm is equipped with a directing-wheel, E, the periphery of which is grooved, and with a guard-wheel, the periphery of which is also grooved, and which is so set with respect to the directing wheel as to constitute, by its groove, a guard to the groove in the directingwheel, so that wire passing around the directing-wheel in its groove is held in place by the guardwheel. The rear extremity of the fccdin the head.

arm is likewise provided with two grooved pulleys, G and H,-between which the wire coming from the reel passes, and around one of which it is first conducted. Both the directing-wheel and its grooved wheel and the grooved pulley serve to conduct the wire as it is led from the wheel both along the course of the arm and to the twisting-hooks, the set of the feed-arm in the set-up of the machine being made such that the directing-wheel at its outer extremity treads against the face of the revolving head, as the latter revolves, at a point in the path of the twisting-hooks. The adjustment of the feedarm is made possible by a nut, d, Fig. 6, applied to the pivot d, upon which the feed-arm is hung. The revolving head is sustained upon a shaft, I), journaled in the standard, to which rotation is imparted through the medium of a bevelgear, I, and pulley J, as seen in Fig. 2. The revolving head is provided with a series of radial slots, 6, within which are contained the devices which serve to twist, cut, and dis charge the wires. These devices in the organization of this machine are the following, one set only being now described:

K is a slide-bearing of any preferred construction, adapted to slide end for end within the slots 1) of the headthat isto say, radially with respect to the head. XVithin the slidebearing is journaled the pinion-shaft L, Fig. 3, which passes through the rim of the head, and beyond said rim is equipped with a pinion, Z, which, in the revolution of the head, engages with the rack M, so as to be revolved thereby.

N is a counter-shaft, also journaled in the slide-bearing and carrying a twisting hook, it. Rotation is imparted to the counter-shaft from the pinion-shaft through the instrunientality of the toothed pinions 0 0, the latter of which is feathered upon the pinion-shaft in such manner as to permit of the endwis'e movement of the slide-bearing and pinion 0 within the slot The slide-bearing is fastened fixedly in any desired position in theslot by means of the bolt 1, the head of which bears against the rear'face of the head through the medium of the bracket-frame T.

Q is the chisel, secured by means of a crosshead, q, upon the projecting extremity of a spring-controlled stem, g adapted to slide through the slide-bearing and project to the rear of the head B through a counter-S10E12, formed parallel with and at the bottom of the radial slot 1/ through the substance of the head. A spring, q, coiled upon the stem between a washer, q, and a cam-head, g serves to bring the chisel down upon a portion of the slide bearing as an anvil after the chisel has been lifted by the action of a camway, U, Fig. 2, fixed with reference to the standard, against which, in the revolution of the head, the camhead g of the spring-controlled stem slides and is lifted. a

S, Figs. 3, at, and 5,is a loop;discharging arm, being a bent wire or kindred device, (shown detached in Fig. 5,)wl1ieh, in the normal position of parts, stands in front of the hook, as shown in Figs. 3 and 4, and which, at its rear extremity, projects to the rear of the revolving head, and is equipped with a toe, s, )rojecting beyond a bracket frame, T, secured in place by the bolt 1?, which fastens the slidebearing. A spiral spring, '6, acts against a collar, 'L, on the arm S, and serves to return the loop-discharging arm to its normal position after the encounter of its toe s with the camway U, or any other suitable camway, which encounter serves to lift said armabnormally above the face of the revolving head, so as to cause the discharge of the looped wire from off the hook.

Such being a description of a preferred construction of my improvements, and it being borne in mind that one set of twisting, cutting, and disehargingdevices of the character above described are employed in connection with each radial slot in the head, it will be readily understood that the operation of the machine is by the engagement in the revolution of the head of the wire fed by the feed-arm by the hooks successively, by the twisting of the hooks through the instrumentalities described, to form the loops, by the cutting of the wire through the throw of the chisels, and by the lifting of the discharging-arm to disengage the wire, the several operations in the set-up of the machine taking place in predetermined sequence.

Each slide-bearing being radially adjustable with respect to the revolving head, it is obvious that the twisting, cutting, and discharging devices can be set at any particular radius, the feed-arm being of course adjusted so that its directing-wheel shall tread in the path of the hooks at whatever radial distance the latter be disposed, with the result that looped wires of different lengths within the area of the revolving head can be produced.

It is proper to state that the form and mechanical arrangement of the parts may be varied, and that the same elements may be combined in essentially the same way and operated to the same purpose, without a literal adherence to the precise form and arrangement hereinbei'ore described.

It is also quite possible for a mechanic so to vary the form and arrangement both of the feedarm and of the slide-bearing and twisting, cutting, and looping devices which it carries, so as to adapt the same for use with precisely the form of machine described in my Reissued Letters Patent hereinbefore referred to.

Having thus described my invention, I claim and desire to secure by Letters Patent 1. In a machine for looping and cutting wire, the following instrumentalities in combination: first, a rotating head provided with devices which are suitably operated to automatically form loops'upon wire and to automatically cut off a given section of looped wire; and, second, a feed-arm supported independently of the head, arranged to overhang the head, and provided at its extremity, which so overhangs, with a directing-wheel, by means of which wire passed around the wheel is in the rotation of the head fed to the devices for forming the loops upon the wire 2. Inamachineforlooping and cuttingwire, the following i'nstrumentalities in combination: first, a rotatinghead; second, devices for forming loops upon the wire; third, devices for outing off a given section of looped wire; fourth, devices for discharging the looped wire from the looping devices; fifth, a device for feeding the wire to the looping devices: and, sixth, suitable means for operating said several in strnmentalities, substantially as set forth.

3. In a machine forlooping-and cutting wire, in combination with a rotating head, devices which are suitably operated to automatically fornr loops upon wire, devices which are suitably operated to automatically cut off a given section of looped wire, the loop-discharging arm S, and means for operating said loop-discharging arm, substantially as set forth.

4. The combination of the rotating headprovided with devices which are suitably operated to automaticallyform loops upon wire, and to automatically cut off a given section of looped wire, of a feed-arm which overhangs the head, and is provided with directing wheels or pullcys, which serve to guide and direct thc'fccd of the wire.

5. In combination with the rotating head provided with radial slots, devices for forming loops upon wire, devices for automatically cutting off a given section of looped wire, means for discharging the cut wires, and means for securing the support and radial adjustmentof said several devices with respect to said r0tat ing head.

6. In combination,the twisting-hooks,means for actuating said hooks to predetermined rotations, the chiscls, means for effecting the pre determined lift and drop of said chisels, the loop-discharging arm, means for securing the operation of said arm. to efi ect the discharge of the looped wires, a slide-bearing or kindred device for containing said assembled devices, a rotating head with respect to which said slide-bearing is radially adj ustahlc, and means for securing theradial adjustment of said bearing and its connected devices.

In testimony whereof Ihave hereunto signed my name this 30th day of January, A. D. 188i.
